Walking is a great way to relieve tension. You can’t beat it for convenience. You can do it just about anywhere, whether you’re at home on the treadmill or taking a quick jaunt home from work. Solo or with friends, you can adjust the pace for almost any fitness level. And because it’s relatively gentle on the joints, people who have had to give up running or other intense sports can turn to walking for their fitness fix.
